    1. A diffraction grating with 2.10E3 slits per centimeter is used to measure the wavelengths emitted by hydrogen gas.
    At what angles in the first-order spectrum would you expect to find the two violet lines of wavelengths 434 nm
    and 410 nm?
    (a) At what angle in the first-order spectrum would you expect to find the first violet line of wavelengths
    434 nm?
    (b) At what angle in the first-order spectrum would you expect to find the second violet line of
    wavelength 410 nm?

    2. What is the longest wavelength that can be observed in the fifth-order (m=5) spectrum using a diffraction grating with
    3.60E3 slits per centimeter? (Unit: nm)
    All answers must have three significant digits unless otherwise specified.
